The story of the 2009 war on piracy was best summarised by another pirate, who lived and died in the fourth century BC. He was captured and brought to Alexander the Great, who demanded to know “what he meant by keeping possession of the sea.” The pirate smiled, and responded: “What you mean by seizing the whole earth; but because I do it with a petty ship, I am called a robber, while you, who do it with a great fleet, are called emperor.”
